SPECIFICATION forming part of Letters Patent No. 305,676, dated September g3, 1884- u Application tiled January 173, 1883. (No modem uTo all whom it may concern,.- i

Be it known that we, JAMEs E. Davrns and JOSHUA H. VOODS, the former a citizen of the United States, residing at Palmyra, county of Portage, and State of Ohio, and the latter a citizen of the United States, lresiding at Alliance, county Vof Stark, and State of Ohio, have invented certain new and-useful Improvements in Rock-Drilling Machinery for 'Oil- 1o Wells, Sie., of which the following is a speciv ication.

Our. invention has for its object, first, to simplify. the construction of parts by means of which the drill is elevated from the shaft being drilled; secondly, to cushion the walkingbeam through which the drill is operated, so

as to steady and prevent the same from jerking 5. and, thirdly, to combine the parts so that Vone side of the derrick will serve asa guide 2o for the walking-beam, and to those ends it consists in the construction `andthe combination of parts'hereinafter particularly described. Figure l is a perspective of the frame having my improvements applied thereto, 'parts being broken away. Fig. 2 is a side view of" the rear portion of the walking-beam, showing its connectionwith the cushioning devices, which are partly in section. Fig. 3 is a side view of the brake and clutch pulley, showing the application of the brake thereto. Fig. 4

is a rear elevation of parts, hereinafter particularly described, detached from other parts.

In` the drawings, the letter A designates a rectangular frame, to one end of which is suitable journaled the derrick B, and to one side of which near the other end are secured the upright posts A A2. To the end of the frame adjacent tothe derriclr there is journaled a shaft, an, to one-end of which is attached the 4Q wheel F, and to the other end the crank d, which is connected by a pitman, e, to one end of the walkingbeain O, which is journaled or pivoted at or near its other end in the diagonal and transverse rods l, 2, and 3, which are connected to the posts A A2, and brace the same. A sleeve, Q, provided with a collar,

a, at one endv to prevent the rope from slipping off the shaft, and a brakepulley, U, at the other end, iits loosely around the shaft m, and

is designed to receive the rope I, which passes 5o over a pulley, b, at the upper end of the derrick, and has the drill D connected to its other end.' The sleeve Q is made fast, so as to turn with the shaft m, when desired, by means of a clutch, W, keyed tothe shaft so as to slide wind or unwind the rope I, according to the direction in which the shaft maybe turned. When the clutch is thrown out from the clutch pulley, the sleeve will remain stationary, to which state it may be brought and held by a brake, V, of the form shown, operated .by 7o a crank-lever, O, having suitable bearings in the frame A. A shaft', It, `ionrnaled in the side pieces of the frame, and provided with a wheel,v

G, at one end, which has; Contact with wheel F so as to be revolved thereby, has connected to it- -one end of a rope, J, which passes over a pulley, b', at the upper end of thederrick, and has attached to its other end the rbucket E, of the ordinary construction, and which is to remove the water and rock-drillings from 8o the shaft being drilled. The wheel F isrevolved by means of a belt, c, passing over the drive-wheel H on the end of the crank-shaft S, journaled in frame A, and Operated by means of a pitman connecting the crank ofthe shaft 8 5 with an engine, neither the pitman nor engine being shown.

The drill D is operated at any desired depth to which it maybe adjusted by rope I by means of the walking-beam C, oscillated through pit- 9o man e, the drill being secured to the beam by means of a suitable device-for' instance, by a staple, T-so that as the beam rises and falls the drill will be raised and lowered with it.

In order that the beam may work steadily without any j erking or j arring,we cushion it by means of springs f `and g, preferably coiled, fitted within two boxes, K and L, secured to e y j 305,616

the posts A andjA2 by bolts or other mean-s, and rods M and N, connected to the beam and acting on the springs in said boxes. The rod M has a washer, h, at its lower end, which rests on the top of spring g, and may be forced down into the same with more or less force to increase or decrease the tension of the spring by a nut, h. The rod N passes down to the lower end ofthe spring f, and at that end is provided with a washer, f', which is made tol bear against the lower face of the spring with more or less force by means of a nut, f2, so as to regulate the tension of the spring. A bracket, i, is bolted to the inside of the upper portion of box L, soV as to be adjustable and' so as to be guided thereby, whereby it is pre-- vented from wabbling sidewise.

The construction is strong, simple, and efflcient for the purpose designed.

Having thus described our invention, what we claim is- 1. The combination of the walking-beam,

'the drill connected therewith, the shaft having the power-wheel at one end and crank at the other end, and the pitman connecting said crank with the beam at the end adjacent to the drill, substantially as described.

2. The combination of the shaft provided with ythe power-wheel and clutch applied to the machine at the' end adjacent to the drill, the sleeve to said shaft, the drill and its rope connected with said sleeve, and the lever for moving the clutch into and out of engagement with said sleeve, substantially as described.`

3. The combination'of the shaft provided with the power-wheel and clutch applied to the machine at the end adjacent to the drill, the sleeve to said shaft, provided with the clutch and brake pulley, the brake to said pulley, the drill and its rope connected with said sleeve, and the lever for moving the clutch into and out of engagement with the clutchpulley, substantially as described.

4. The combination of the shaft provided with the power-wheel and clutch applied to the machine at the end adjacent to the drill, the sleeve to said shaft, the drill connected with said sleeve by the rope, the shaft provided with the wheel in contact with the powerwheel, the bucket connected with said shaft by the rope, and the lever for moving the clutch into and out of engagement with said sleeve, substantially as described.

5. The combination of the beam, the powershaft connected therewith by a pitman at the end of `the machine adjacent to the drill, the

drill connected with the beam, and the sleeve to the power-shaft, connected with the dril-l and capable of revolving or 4not revolving with the shaft, substantially as described. j

6. rlhe combination, with the walking-beam, of a spring-cushion consisting of two springs,

one of which is expanded whenthe other is l' compressed, for steadyingand preventing the beam from jerking, substantially as described.

7. The combination, with the beam, of the springs, therods connecting the same and the beam, boxes for the springs, and supports for the boxes, substantially asdescribed.

8. The combination, with the walking-beam, c

of a spring-cushion consisting of two springs, the tension of which is adjustable, one yof which is expanded when the other is compressed, for steadying and preventing the beam .from jerking, substantially as described.

9. The combination of the beam, the boxes, the springs lwithin the boxes, the rods con'- necting the'beam land springs, and the nuts for regulating the tension of the springs, substantially as described.

l0. The combination, with the walkingbeam, of the derrick having one side at one end of the machine adjacent to the drill formed to act as aguide to the beam in its movement, substantially as'described.
